The interesting part is I think the M40 actually can achieve FIRE as easily, if not more, vs the T20. As long as they don't have the urge to keep up with the Jones.
The numbers (we just have to believe them) don't lie. M40 individual median income is only 3.4K rm per month. 3.4K x 12 x 25 = 1 million.
Incidentally, if one start working at age 20 with salary of 2K pm, contribute to EPF and never take out, salary incement of just 1.5% pa, one's salary at age 60 will reach 3.6K rm pm. With avg div of 5.5%, EPF balance will reach 1 million at age 60.
My own criticism would be how easy is it to get a salary of 2K rm at age 20 back in 1983. Then again, 1.5% pa increment of salary only doesn't make sense too. There must also be other savings/investment outside of EPF too.
(a old ex-colleage of mine told me that she started her career at around 1980s, and her starting pay was 1.4K rm pm.)
Another key point.
For the M40 persons, their FIRE number should be closer to 3K rm per month.
While for the T20, their number would be much higher at say 8K rm per month.
A M40 person die die wants a FIRE number of 20K rm per month is a person who doesn't realize what FIRE is all about. Such person should continue to work harder to achieve a
status upgrade, rather than look at retirement.
i'd say M40 almost impossible to achieve financial independence... so cannot retire early... T20 have achieve financial independence... but do not WANT to retire early...
